THE SOLUTION

Mission Statement

SimActive’s mission is to constantly develop and market cutting-edge technologies that simplify and enhance geospatial

data production

Growing Challenges

Expensive• Only 30% project

costs for data acquisition, remaining 70% associated with

production

Skills and Knowledge• Highly-trained

personnel required

Not User-Friendly

• Complex software tools

Geospatial Data

Production

Long Process• Several months

usually required for data delivery

Design Criterion: Keep it Simple!

Benefits in a Nutshell

FASTER...• Up to 60 times faster than currently available tools• Data production can be performed in parallel on multiple machines• Software designed to quickly process thousands of images

EASIER…• Minimal software and data manipulation requirements• Highly-trained personnel are no longer required, virtually no parameters to set• Easy integration into any third-party workflow

BETTER...• Better geospatial data at the fraction of the cost• Uses advanced computer vision algorithms• Produced data are ready-to-use• Cost-effective alternative to LIDAR data
